Anyone else: Tune transformed the car, but what should I log?

Running a conservative tune and the car feels great. I don't want to judge reliability by seat-of-the-pants though. Which parameters would you log periodically—fuel trims, knock, boost target, temperatures, something else? Appreciate any ideas on what to check first.

Thanks — that narrowed it. I'm going to try the simpler check on the 2024 BMW i4 first. Wrote this up on my lunch break.

I'd wait for the actual TSB/recall population, not the headline. If this is a 2027 reveal, I wouldn't map it onto today's 2024 BMW i4 ownership costs yet. That's where I'd start. I'd want a dollar figure or a measured spec, not 'should be fine.' Doing the boring step first on purpose.

New-model numbers always look better than curb weight and tire size. On a 2024 BMW i4, I'd care more about the remedy and downtime than the press wording. That's where I'd start. This is from a 2024 BMW i4 in Texas. I'd want a dollar figure or a measured spec, not 'should be fine.' A day of patience here is cheaper than a wrong part. If the story changes I'll post the new data.

On “tune transformed the car, but what should,” that was the fork that mattered for me. Happy to compare notes if your setup is different. Wrote this up on my lunch break.

Agree — and I'd add this: On a 2024 BMW i4, I'd care more about the remedy and downtime than the press wording. I'd do that before spending real money. If they can't show the line item, I assume it's hiding. Might be overthinking it, but I'd rather overthink than overspend.

I parked the 2024 BMW i4 and wrote down what I already tested so I'm not repeating myself. Doing the boring step first on purpose.

Software recalls make me ask how much of 'driving' lives in a module now. Check whether your 2024 BMW i4 VIN is actually in the affected batch before you plan a dealer day. I'd do that before spending real money. If you share a photo of the worksheet, easier to sanity-check. This is me being the wet blanket on purpose.

Yes, with one caveat: On a 2024 BMW i4, I'd care more about the remedy and downtime than the press wording. I'd do that before spending real money. On “tune transformed the car, but what should,” that was the fork that mattered for me. Post the numbers (or the code) and people can get more specific. That's my plan before I call anyone.

If it doesn't change the out-the-door or the repair estimate, it's noise. I'm keeping receipts and dates in one folder.
